B2222 on Lexus
Right Front Door Lock/Unlock Switch Stuck
B2222 on Lexus vehicles indicates right front door lock/unlock switch stuck. Au7o has documented this code across 1 Lexus model — most commonly on LX. B2222 is a body code, commonly defined on GM-family vehicles as the right front (passenger) door lock/unlock switch being stuck or reporting an invalid state. The body control module monitors the switch input and stores the code when it detects a continuously held or implausible lock/unlock command. It generally affects only the power lock convenience feature and is not safety-critical. Typical repair costs on Lexus range from $250 to $1,800, depending on the specific model and root cause.
Common Causes of B2222
- •Stuck or shorted passenger door lock/unlock switch
- •Worn or dirty switch contacts
- •Wiring short to ground or voltage in the circuit
- •Corroded or damaged door harness connector
- •Water or debris intrusion into the switch

- Power Tailgate / Rear Hatch Fails to Open or Close Properly Due to Latch or Strut/Module Faults2022-2025
Owners have reported intermittent operation of the LX split rear hatch/power tailgate system, including failure to open, failure to cinch closed, or warning messages indicating the rear door is open when it appears latched. On a vehicle with a complex powered rear closure system, faults can stem from latch alignment, pinch sensors, control modules, or weak power strut behavior. The issue is inconvenient and can create security or battery-drain concerns if the vehicle thinks the hatch remains ajar.
